stm32f103c8t6接振动传感器将振动信号发送到示波器代码

首先，STM32F103C8T6是一款基于ARM Cortex-M3内核的微控制器，它具有丰富的外设和强大的计算能力，非常适合用于嵌入式系统的开发。

接振动传感器将振动信号发送到示波器的代码，需要涉及到以下几个方面：

1. 硬件连接：将振动传感器连接到STM32F103C8T6的GPIO口上，通常使用中断方式来采集振动信号。

2. 采集振动信号：在STM32F103C8T6上编写中断服务程序，通过GPIO口采集振动信号，并将采集到的数据存储到缓冲区中。

3. 处理振动信号：对采集到的振动信号进行处理，例如滤波、放大、去除直流分量等。

4. 发送数据到示波器：将处理后的振动信号数据通过串口或者其他通信方式发送到示波器上进行显示。

下面是一个简单的示例代码，仅供参考：
